REINFORCED PRESS-CLOTH.

To all whom it may concern:

Be it known that I, FRANKLIN T. PARKER, a citizen of the United States, residing at Columbia, in the county of Richland and State of South Carolina, have invented certain new and useful Improvements in Reinforced Press-Cloth, of which the following is a specification.

This invention relates to oil-press cloth. Ordinarily the cloth used in cotton-seed and other presses is hair and wool cloth and while intended to withstand the enormous pressure to which it is subjected in the operation of the press, without bursting, it is generally found that such cloths after having been in use but a very short period of time become frayed or unraveled and finally burst, particularly at the line of fold in the cloth, it being understood that a strip of the cloth is folded transversely between its ends to form a mat within which the cake of crushed seeds is placed prior to the pressing ion. Due to the nature of the material from which these cloths are woven, their frequent replacement is a considerable item of expense. The present invention therefore has as its primary object to provide a presscloth which may be manufactured in any suitable length and width and which will be so finished that any desired length there'- of cut from the bolt or roll to provide a mat, will possess features of reinforcement which will provide against bursting of the mat during the pressing operation and will also provide against rapid wearing through of the cloth of the mat or fraying of the said cloth.

In the accompanying drawings:

Figure 1 is a plan view of a portion of a bolt or roll of cloth embodying a reinforcement of one character;

Figs. 2 and 3 are similar views illustrating modifications of the reinforcement shown in Fig. 1;

Fig. 4 is a view similar to Fig. 1 illustrating another arrangement of reinforcement;

Fig. 5 is a view similar to Fig. 4 illustrating a modification of the reinforcement shown in the said figure.

In all of the figures of the drawings the numeral 1 indicates the cloth, preferably hair and wool cloth, woven in a piece of any desired dimensions, the cloth for example being manufactured in rolls or bolts having a width'equal to the width of the usual mat Specification of Letters Patent.

employed in cottonseed and other oilpresses, and of any desired length so that in order to prepare a mat it is only necessary to cut from the roll or bolt a piece of cloth of the proper length.

In the simplest form of the invention, illustrated in Fig. 2 of the drawings, the cloth is reinforced by running one or more lines of stitching 2 through the cloth, the lines extending parallel to each other if of plural number and in any event parallel to the longitudinal edges of the cloth. Any kind of thread may be employed in forming the lines of stitching and, of course, the lines may be single, double, etc., and also the particular kind of stitch made is immaterial.

Another simple embodiment of the invention is shown in Fig. 3 of the drawings and in this embodiment the cloth is reinforced by running one or more lines of stitching 3 through the cloth, each line of stitching following a sinuous course, but extending generally longitudinally of the cloth. Thus a single line of stitching may be run through the cloth in a sinuous manner, being carried back and forth along curving lines as it is also carried longitudinally, or two or more such lines may be run as shown in the said Fig. 8. Thus for example if two such lines are run through the cloth each will lie wholly between one longitudinal edge of the piece of cloth and the longitudinal median line of the said piece of cloth and it is probable that the arrangement which will be preferred and which is illustrated in the said figure will consist in so running the lines of stitching that these lines will alternately approach and recede from each other and likewise alternately approach and recede from the respective or adjacent longitudinal edges of the piece of cloth.

Fig. 1 of the drawings illustrates a combination of the two reinforcing stitchings shown in Figs. 2 and 3 of the drawings. That is to say in the form shown in Fig. 1 longitudinal parallel lines of stitching 4 corresponding to the lines of stitching 2. and sinuous or serpentine lines of stitching 5 corresponding to the lines of stitching 3 will be run through the cloth, the lines 4 and 5 intersecti g in the manner shown in the said Fig. 1. Of course, this latter method of reinforcement of the cloth will render the cloth mu h stronger than when reinforced by the two previously described methods.

this being, of course, due to the presence of the greater number of lines of stitching in the cloth and. the fact that the lines are so extended that those of one kind will intersect those of the other at various points in the length of cloth.

Fig. 5 of the drawings illustrates an arrangement somewhat similar to that shown in Fig. 3, two lines of the stitching 6 being run through the cloth, each line taking a zigzag course and the lines intersecting as at 7 between the bends in the lines. Furthermore in this embodiment the lines run substantially the full width of the cloth as well as longitudinally thereof as distinguished from the embodiment shown in Fig. 3 in which each line runs approximately only one-half the width of the piece of cloth.

The modification shown in Fig. A embodies lines of stitching 8 corresponding to the lines 6, and other lines of stitching 9 corresponding to the lines 2 .shown in the previously described Fig. 2. In other words, this embodiment constitutes a combination of the arrangement of. reinforcing stitching shown in Figs. 2 and 5 of the drawings and possesses the advantages peculiar to the embodiment shown in Fig. 1 of the drawings and which advantages are above recited.

reinforced by intersecting lines of stitching.

4C. Asa new manufacture, oil-press cloth reinforced by'intersectlng lines of stitching extending in the general dlrection of the length of the cloth.

5. As a new manufacture, oil-press cloth reinforced by substantially parallel lines of stitching extending longitudinally there of and other lines of stitching intersecting the first mentioned lines. 4

6. As a new manufacture, oil-press cloth reinforced by substantially parallel lines of stitching extending longitudinally thereof and by a sinuous line of stitching intersecting the first mentioned lines and extending in the general direction of thelength of the cloth.

In testimony whereof I afiiX my signature.
